Experience

  • Lottery.com App
    https://lottery.com

    I worked on this app from 2016 until 2019. At first, when I joined the team, I was tasked to make the user interface look excellent along with various refactors and bug fixes. When we converted the entire front end to React Native, I was in charge of making sure that the iOS-dependent modules worked as intended.

  • Stamena

    I worked as the sole developer on a Swift-based strength training app. I worked with one designer and had full reign over the underlying software architecture. This project took about two weeks to complete.

  • 360 Rotating Photo Timelapse

    This was a personal art project that turned into a significant software challenge consisting of three parts. First, I created an iPhone app (pure Swift) to take videos of a rotating subject at fixed time intervals. Second, I wrote a command-line tool (Bash and Python) to align the videos with some computer vision techniques and convert them to usable image sequences. Third, I created an After Effects plugin (C++, OpenGL, and GLSL), which allows the images to be previewed and rendered directly from Adobe After Effects. (The result is pretty darn cool, I think!) I can control time and rotation independently and do some unique effects with this technology.
